摘要(Abstract):

微电网通常由负载、储能系统以及分布式发电单元组成。由于其惯性小和不确定性大的特点,微电网控制一直是研究的难点。针对微电网中的并联分布式发电单元提出了一种分散式控制算法,提高了分布式发电单元之间的负载电流分配精度,并使系统的母线电压可以跟踪电压参考轨迹。最后,仿真结果验证了所设计控制算法的有效性。
A microgrid generally comprises load units, energy storage systems and distributed generation units. Microgrid control has always been a difficult research point due to its low inertia and great uncertainty.In this study, a decentralized control algorithm is presented for paralleled distributed generation units in microgrids to enhance the load current sharing accuracy among the distributed generation units and enable the bus voltage to track the voltage reference. Finally, the simulation result verifies the effectiveness of the developed control algorithm.
